I know everyone is different but I was curious if this sounded "normal". My JR high years I had crazy discharge where my panties would constantly feel wet but it's better now. Every once in a while I'll get a little wet feeling throughout the day. By the end of the day I'll have white marks in my panties. It's normal for me. Is that how it is for every girl?
Also I usually wear the thinnest pantyliners daily. Is that weird?
My wife's OBGYN said that a normal, healthy woman will have a spot in her panties at the end of the day from vaginal lubrication.
Better get an OBGYN consultation and get a recommendation from the experts when situations like that happen, or if something weird happens to your organs. Like what I always tell my wife, I always remind her to go to a Gynecologist in Memphis for a regular OBGYN checkup. Remember, "prevention is better than cure".
